Waste compaction

Main compaction is produced by the landfill compactors steel tooth on the wheel drums.

Special teeth can penetrate the waste and deliver a focused compression point, providing compaction and increased density.

Ground pressure of the tooth can exceed over 4,000 pounds per square inch (28,000 kPa) (PSI).

Loose, non-compacted trash occupies up to 20 times more dumpster space than compacted waste.

A side effect of waste compaction is that important items, like evidence in a crime, may be difficult to recover from the garbage.
